This game seems, from its itch page, to have been made as part of a doctoral program.
It's a bipsi/binksi visual novel and includes the original poem with some of the original drawings that Lewis Carroll included in his book. It also includes a branching portion where you explore the world described in the poem, with multiple endings.
I got two bad endings; I think I know how to get the good ending, but I was hitting the arrows fast to get through the text quickly and ended up treading dark paths.
Overall, its competently done and reworks a poem I loved as a youth (I liked it when I was older too when I saw how translators translated it). I think I might have liked more long-term effects of choices to allow strategizing, but overall this is pretty good.
